Title: Device for introducing gas into liquids, in particular a liquid/solid suspension with added flotation reagents
Inventor: IMHOF RAINER DR
IPC: B01F5/04
Filed: 1983-07-19
Abstract: In introducing gas into liquids, in particular a liquid/solid suspension with added flotation reagents, the feeding of the gas introduction medium into the suspension can already take place in the suspension feed lines before they are passed into the actual separation vessel by means of injectors or gas-permeable bodies within gas introduction devices. Known gas introduction devices have, however, poor reproducibility, particularly with respect to the quality of equal gas permeability and, on the pulp side, tend to block fine pore passages by deposition of particles. A gas introduction device (1) according to the invention is characterised in that the orifices (6) are formed in the region (4) of feeding the gas introduction media by mutually spaced leaves (5) arranged in successive rows. In this gas introduction device, the same pressure conditions apply at all orifices at the gas introduction media/suspensions phase transition, so that a continuous introduction, which remains constant, of equally large or equally fine gas bubbles into the suspension is ensured. <IMAGE>

Title: Sheet-metal layer-forming device for forming the layers of iron cores, and a method for forming the layers of the same
Inventor: GRAUL OTTO
IPC: H01F41/02
Filed: 1984-01-25
Abstract: In the case of a sheet-metal layer-forming device for forming the layers of iron cores which are assembled from individual metal sheets, it is intended to achieve the object of constructing this sheet-metal layer-forming device such that accurate metal sheet removal from the metal sheet stack can be carried out and such that the raised metal sheet can be placed down on the iron core of which the layers are to be formed likewise accurately and as far as possible without an air gap. For this purpose, the previously lifting gripping element (2') is supported in a pendular manner via an upper pivoting bearing (20) in such a manner that this gripping element (2') can be pivoted towards the gripping element (2) which is not raised as a consequence of the shortening of the distance between said gripping element (2') and the gripping element (2) which is not yet raised, which shortening occurs as a result of the S-shaped bending. <IMAGE>

Title: Device for transferring individual blind rivets
Inventor: ELFLEIN MANFRED
IPC: B21J15/34
Filed: 1984-03-09
Abstract: A description is given of a mechanised device for transferring individual blind rivets to a blind-rivet setting appliance, the said device considerably simplifying and shortening the transfer operation. For this purpose, a feed device, which separates the blind rivets and aligns them in each case in the same direction with the mandrel projecting forwards, is connected to a feed duct. At the end of the feed duct there is a blocking device, which can be pivoted between a through position and a blocking position, essentially the entire cross-section of the feed duct being exposed in the through position and the said duct being closed apart from a centering hole in the blocking position. The blocking device is actuated by a control device which simultaneously controls the feeding of the blind rivets. The control device in turn is actuated by the insertion of the blind-rivet setting appliance into a taper sleeve and thus triggers the transfer operation.

Title: Antenna element consisting of glass-fibre-reinforced plastic tubing with a metallic coating
Inventor: RIEDER JOACHIM
IPC: H01Q1/38
Filed: 1984-03-14
Abstract: Antennas are an indispensable part of every radio transmitting and receiving system. There are therefore a multiplicity of designs, which all have advantages and disadvantages. The invention relates to antennas in the short-wave band and here, in particular, to multi-element designs which can rotate. The advantages of such systems in radio terms are known. However, it is difficult to produce such designs easily and nevertheless robustly. The elements of such antenna systems are in addition frequently interrupted by coils or blocking circuits, which likewise increases the risk of fracture. Aluminium tubing is used virtually exclusively as the material for these designs. Although the tubes become more robust with greater diameters, they are, however, heavier and more expensive. Glass-fibre-reinforced plastic tubing is offered as an alternative. The mechanical properties of this material are excellent and the weight is considerably lower. Since this material is also a very good insulator, an antenna element consisting of such material does not need to be interrupted at the points of coils or blocking circuits. The problem in the case of this material is the actual antenna conductor. A wire could be inserted for this purpose. However, as a consequence of its high slenderness ratio this gives the antenna a very narrowband nature, which is undesirable in the case of most antennas. In addition, the wire must be fixed centrally in the tubing since, in the event of a change in the distance from the wall, the tuning of the antenna ... Original abstract incomplete.

Title: Roofing
Inventor: REINHARDT WALTER
IPC: A01G9/14
Filed: 1984-05-26
Abstract: The invention relates to a modular-type roofing, composed of individual prefabricated parts, such as a winter garden, terrace extension, summerhouse, greenhouse or the like with a wall, extending upwards from the floor, and a roof. The wall and the roof are formed in each case essentially from panel-shaped wall segments (3, 4, 5) and roof segments (14, 15, 18), respectively, consisting of transparent material, in particular plastic. All the segments are in the form of a triangle and are arranged with respect to one another and connected to one another in such a manner that a self-supporting structure results. In the case of the wall, first wall elements (3, 3') are situated next to one another with their points directed upwards. These wall elements form triangular interspaces which are respectively covered by a pair of second wall segments (4, 5). The latter are at an angle with respect to one another in horizontal section and form an external angle jutting out in front of the plane of the first wall segments (3). The wall-side edge of a roof segment (14, 15) is in each case connected to the roof-side edges of the second wall-side segments (4, 5). Starting from the zig-zag eaves line, the roof segments run inwards in an inclined manner up to a roof-ridge line. The pairs of roof segments either adjoin one another directly or are connected to one another via a first roof segment (18), the point of which is arranged at the respective internal angle of the eaves line. <IMAGE>

Patent DE-3427421-A1 (DE)
Inventor: RIZK REDA R
IPC: F02M59/46
Filed: 1984-07-25
Abstract: A control valve for a fuel injector, especially of an air-compressing, spontaneous-ignition, internal combustion engine. The control valve includes a valve body in the form of a piston valve which is axially movable in a housing chamber into a closure position and an open position, with the closure position being determined by a valve seat on the housing, and a seating surface edge on the piston valve. The housing chamber includes at least one high pressure connection, and a low pressure connection. The basic problem with a control valve of this general type is that when the piston valve strikes the valve seat, rebound movements are carried out by the piston valve, so that the closure position can only be reliably assumed after a certain time delay, thus negatively influencing the injection process. In order to avoid these drawbacks, it is possible to have the valve housing chamber, either between its valve seat and the high pressure connection on the one hand, as well as the high-pressure side of the piston valve adjacent the seating surface edge on the other hand, or between its valve seat and the low pressure connection on the one hand as well as the low-pressure side of the piston valve adjacent the seating surface edge, each being provided with a portion having the same diameter. Alternatively, an attenuation mass, especially an attenuation piston element, can be provided on and/or within the piston valve, with this attenuation mass being movable relative to the piston valve.
